Paying homage to the annual migrating Canada geese flying overhead, it is apt to discuss the unusual balance that exists around Chesapeake Bay between hunting and conservation.

I spotted a whole pallet of discounted ammunition, akin to a half-priced pallet of washing detergent you might see in an Australian supermarket.

Having worked as an investigator with the former Queensland EPA in Australia, I was gob-smacked by the progressive way that the U.S. EPA deals with environmental crime.

Keep your eye out for "climate disruption" in the media.

Brisbane and Brisbane River are named after Sir Thomas Brisbane, a Premier of New South Wales before Queensland was created. Moreton Bay was named by Captain James Cook as he sailed by in 1770.

The close relationship that Australian cities have with their waterways is due to several factors. The majority of Australia's population is along the coast as a result of proximity to shipping, moderate climates, availability of freshwater and lifestyle preferences. The waterways have been a source of water, food and transport since early European settlement and for the prior forty thousand years of indigenous peoples on the continent.
